fix checksum mismatch with trailing slash
fix checksum mismatch with trailing slash

With ansible 2.3 ims-dump fails with
"checksum mismatch" because
the destination is a directory,
but has no trailing slash.

This is fixed in ansible 2.4
in a way that still fails,
but changes the error message.

So we just add the trailing slash.
